CAN-'OPENEFLk Specification of Letters Patent.

Patented Jan. 9, 1906.

Application led June 13, 1905. Serial No. 265,084:-

TO all whom, it nung concern:

Be it known that I, J AMES WALTER DAvrs,`

This invention relates to a can-opener, and

particularly to a structure in which the can is rotated into contactwith a cutting-blade.

The invention has for an object to provide a construction for supportinga can and moving the same into contact with a cuttingblade and aftersuch contact rotating the can to remove the head therefrom.

Other and further obj ects and advantages of the invention will behereinafter set forth, and the novel features thereof defined by theappended claims.

In the drawings, Figure `1 is a perspective of the invention; Fig. 2, aside elevation of the standard supporting the circular canopener; Fig.8, a plan of the can-support, and Fig. 4 a detail perspective of thecuttingblade.

Like letters of reference refer to like parts in the several figures ofthe drawings.

The letter A designates a base-plate of any desired construction orconfiguration, which is provided at one side with a standard A extendingupward therefrom and provided with a laterally-extending head A2.Intermediate of this head and the base is a threaded arm A3, throughwhich the screwB passes, and is provided at its upper end with acanholding plate B secured thereto, while the lower end of the screw isprovided with an operating-handle B2, as shown. The upper face of thecan-holding plate B is provided with any desired means, such as aroughened face B2, for preventing a slipping or relative movement ofthecan thereon. as the parts are rotated, one form of which is shown inFig. 3.

The head A2 is provided with a longitudinal slot A2', as shown by dottedlines in Fig. 2, and also with a depending centering-pin A4, adapted toengage the can as the same is forced upward into contact with thecuttingblade C, which is supported in the slot A3 by means of its shankC extending through the slot and provided with a clamping-nut C2 uponthe upper face of the head. The cutting-blade is thus adjustably mountedfor movement relative to the centering pin, whereby an opening ofdifferent sizes may be made in the can, as found desirable. Thiscutting-blade is sharpened upon its opposite edges, as shown in Fig. 4,and provided with shoulders C3, which rest against the under face of thehead to support the blade and to permit its reversal in order to useboth edges thereof.

For the purpose of supporting the rectangular cutter D in position thebase A is provided with upwardly extending lugs A, spaced apart and tothe upper ends of which the side bars D are pivotally connected, eachbeing provided with a knife or cutting edge D2, while the end bar D3 ofthe frame is provided with a similar edge D and with an operating-handleD5. The base is formed with a stop-fiange A6v at its end next thehandle, against which the end of the can abuts when it is placed beneaththis cutter.

In the operation of the invention the can is supported upon the platecarried by the screw, which when rotated carries the can upward until itengages the centering-pin and cutterblade, at which time the continuedmovement of the screw causes these points to puncture the can-top, andowing to the rotary movement of the can the blade continues its cut in acircular path until the top is severed from the can, when the parts maybe quickly Withdrawn by reversing the direction of rotation of thescrew.

The invention presents a simple and eflicient construction for yquicklyopening Vcans Y and avoids the necessity for holding the can in the handor for manually operating the cutter-blade during the opening, thusobviating the soiling of the hands and the contact of liquid or othercontents of the can and also the frequent injury caused by slipping of ablade of the opener when carried by the hand.

Having described my invention and set forth its merits, what I claim,and desire to secure by Letters Patent, is-

l. Abase provided with astandard having a laterally-extending head, acutting-blade fixed to said head relative to a can, a supporting armcarried by said standard, a screw mounted upon said arm, and acan-support secured to the upper end of said screw to rotate therewithand move the can into cutting relation with said blade.

IOO

2. Abase provided With a standardhaving va laterally-extending head, acutting-blade fixed to said head relative to a can, a supportingarmcarried by said standard, a 5 screw mounted upon said arm, a can-supportsecured to the upper end of said screw to rotate therewith and move theoaninto out ting relation With said blade, a centering-pin carried bythe head in alinernent With said screw, and means for adjusting saidoutting- Io blade relative to said pin.

In testimony whereof Iyafx my signature in presence of two Witnesses.

JAMES WALTER DAVIS.
